HENRY PETERSEN, OF MOUNT AUBURN, IOWA.

DRAFT-EQUALIZER.

To all whom it may concern Be it known that I, I'IENRY Pn'rnnsnn, a citizen of the United States of America, and resident of Mount Auburn, in the county of Benton and State of Iowa, have invented certain new and useful Improvements in Draft-Equalizers, of which the following is a specification.

This invention relates to certain new and useful improvements in draft equalizers or eveners of that class in which the usual horizontal doubletree pivoted upon the tongue is dispensed with, and it has for its objects among others to provide a simple and improved form of draft equalizer or evener which, while designed principally for use on a cultivator or plow, is not necessarily restricted to use upon such class of implements, being capable of use in any and all positions and upon any and all classes of draft vehicles where such devices are desirable.

It has for a further object to provide a draft equalizer of this general character embodying oscillating bearings which are independent of each other and the construction being such as to prevent buckling of the equalizer under the cultivator or other implement from strain.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention iscapable of embodiment in a variety of forms all embracingthe same generic feature, namely the independent oscillatory bearings, a few examples of which are illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a draft equalizer constructed in accordance with my present invention and shown applied to a cultivator. Fig. 2 is a top plan thereof. Fig. 3 is a perspective detail of one-half of the equalizer with a portion broken away. Fig. 4 is a perspective view showing a modified form of equalizer. Fig. 5 is a cross section on the line 55 of Fig. 4 looking in the direction of the arrows. Fig. 6 is a perspective view of still another form of the invention. Fig. 7 is a plan View thereof.

Like numerals of referenceindicate like parts throughout the several views.

' Referring to the drawings, ldesignates I Specification of Letters Patent.

the tongue which, shownin Fig. 1, may be that of a cultivator of any well known form, of which 2 is the gang frame, or it might be a plow beam or other portion of a different sort of draft vehicle.

Referring first to the construction shown in Figs. 1 and 2, 3 are horizontal members secured to the under side of the rear end of the tongue in any suitable manner, as by an ordinary clip, and these may be tubular or solid, as may be preferred. They serve as supports or bearings for the oscillating members of the evener. In the form shown in Figs. 1, 2 and 3 these bearings 4 are of tubular form and are sleeved upon these horizontal projections 3, 3, so as to oscillate freely thereupon. Rigid with and depending from, and integral with if desired, each member 4 is the member 5, the lower end of which has the horizontal extension 6 provided with a plurality of openings 7. On each member 5 are the bearings 8, properly spaced and in each pair of which the vertial rock shaft 9 is mounted to freely turn. The lower end of each rock shaft 9 is extended substantially horizontally, as seen at 10, and provided with an opening 11 for the attachment of a swingletree 12; the up per ends of the rock shafts 9 have the horizontal extensions 13 which, as seen in Fig. 8, are disposed substantially at right angles to the horizontal portions 10, and to the outer ends of these horizontal extensions 13 Fig. 1. The operationwill be apparent and,

as seen in Fig. 1, the vertical members 5 are normally extended forward of a perpendie ular and the gang frame is in the position shown in full lines. When the lever of the cultivator is operated to throw the gang frame up, the vertical members 5 are thrown rearward into the position shown in dotted lines, the chains 16 permitting the gang frame to assume the position indicated in dotted lines.

Another form of the invention is illustrated inFigs. 4 and 5. In this form the tongue 1 is provided with the tubular extensions 3 near the rear end and the verti cal rock shafts 17 for the lateral members 18 at their upper ends which are received within said tubular extensions, thus forniing independent oscillatory bearings, the parts simply being a reversal of what is illustrated in Figs. 1, 2 and 3, the operationand resultbeing, however, the same. These rock shafts have sleeved thereon the tubular vertical members 19, the upper ends of which mernbers '19are held against verticalmovementupon the rock shaftsl? by the sleeves or collars 23 provided with the set screws or thealike .24,-permitting of. their removal when desired. These vertical tubular'memhers-19 are provided with the longitudinal ribs 25 which are received in grooves 26 in the collars 27 embracing said verticalmomhers-19 and provided with the lateral memance with the foregoing description is simple, of few'parts, most efficient and reliable in operation and whilefthe structural em here 28 having at their outer ends openings 29-for the attachment ofswingletrees. The lower ends of the members l'Z-are provided with the lateral portions 30 having openings 31 for the connection of chains or the'like by which they are attached-to the lower forward portion of the gang frame as are the members .6 inthe form shown in Fig. .1. Set screws 32 maybe provided, if desired, for holding the collars 27 at the desired height upon the tubular members '19.

In Figs. 6 and 17 I. have shown still another iform ofembodiment of the invention,

in-which the tubular members 3, 3 are presentas beforeand uponthe same are sleeved th-etubular-bearings 33 adapted to have independent oscillat-ory; movement the same as in. the form shown i l igs. 1 to 3 and in Figs. f and 5. Each tubular bearing has afrigiddepending arm 34 with a lateral portion of the gang frame. mounted upon the-under. side of'the tongue uponva suitable .pivot 37 is an evenerfbar 39 are links connected at their-forward ends -pivotally With. the opposite ends of which are attached at abouttwo-thirds of the 'evener-bar 38. and theirother ends pivotallyconnected, as at 40, with the upper end of the substantially. v'erticalmembers 41 the distance from their lower ends, as at 42, to; the horizontal arms or bearings 43 attached to theemembers 34 and 4:1,- as seen clearly at the leftwofllig. 6-. The mode of operation is" substantially the. same. in all ofathe forms :herei-nbefore described. It is to benotedthat thelatejralextensions 6, 30 and 35 are provided with a plurality of openings 50 that :thechains may be attached nearergto or farther. from; thehorses as occa- SiOn? may require, J to prevent. crowding in orout of the gangs- 1 'Ilhe supports. of the i oscillatory may be mounted on the frame or tongue; the depending members serve as they pivotal seat for the draft strain equalizer or evener, and they also serve to divide the draft straimqaartlyon-themain frame and partly ventedby the adjustable connection between the lower ends of the depending members and the gang frame. It is evident that the adjustment may be provided for at either the extensions or at the gang frame, the result being the same.

A draft equalizer constructed in accordbodiinentsof the same as hereinbefore dis- .closed are what I at the present time consider preferable, it is evident that the same is subject to changes, variations and modifications in details, proportions of parts,'etc. without departingfrom the spirit of the invention or sacrificing any of its advantages.

I, therefore, do not desireto limit myself to the exact construction, arrangement of parts and details hereinbefore disclosed, but reserve the right to make such changes, .varia tions and modifications as come properly within .the scope of the protection prayed.
